Looking at how long it's taking to reach your "graphical.target", Do this, even though it was written at the time of Ubuntu 18.04. It works, even Ubuntu 20.04 (There are two methods; use one or both):
Method One
Type (in the terminal):
$ sudo sed -e 's/^RESUME=/#RESUME=/g' \
-i /etc/initramfs-tools/conf.d/resume
After that is finished, type:
$ echo "RESUME=/dev/mapper/ubuntu--YOUR FLAVOR OF UBUNTU (eg. mate)--vg-swap_1" | \
sudo tee -a /etc/initramfs-tools/conf.d/resume
Recreate initrd and reboot system.
$ sudo update-initramfs -u
After that is finished, type:
$ sudo reboot
The kernel boot time should be faster. Verify by typing:
$ systemd-analyze
You will also be able to use hibernation after this.
Method Two
Navigate to /etc/initramfs-tools/conf.d/
Right click on "resume" and choose "Edit as Administrator". Измените строку:
RESUME = UUID = В зависимости от того, что вы номер (ex - RESUME = UUID = 67b3fe6f-1ec4-413f-8c5a-1136bc7f3270)
Кому:
RESUME = нет
Теперь откройте терминал и введите:
$ sudo update-initramfs -u
После этого введите:
$ sudo reboot
Время загрузки должно быть быстрее.
